Portion of test results: Running target unix Using /usr/share/dejagnu/baseboards/unix.exp as board description file for target. Using /usr/share/dejagnu/config/unix.exp as generic interface file for target. Using /disk3/extsrc/gcc-4.5.1/libstdc++-v3/testsuite/config/default.exp as tool-and-target-specific interface file. Running /disk3/extsrc/gcc-4.5.1/libstdc++-v3/testsuite/libstdc++-abi/abi.exp ... FAIL: abi_check That's the only failure I got for languages c,c++,fortran. I searched the test results at <http://gcc.gnu.org/ml/gcc-testresults/> and found similar failures but I haven't found any discussion on the gcc list since 2009-10. Any ideas? Thanks. -Tom Thomas M.
